Feb 23, 2011
My requirement is i need to display some quotes from some vendors in my User Interface. Some of the quote details will be fetched from database where as some vendors are giving web services to get the quote results. I need to combine the quotes from database as well as the various web service response and display in the grid.

I make an asynchronous call from one web service to another web service deployed on different server? The scenario is that an ASP.NET webforms page will call a web service in an async manner. This particular web service will then make another async call to a second web service deployed on different web server. This this possible to achieve, and what additional steps or code would be necessary to make this happen?

i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.
And, client "c1" seperately asks seperately how will be the authendication architecture.
so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.

recently i've studied on ADO.NET's Entity Model Framework and say 'wow' as ORM is one of the fevourite pattern i practice..but suddenly i've come to an ambiguous situation when i'm going to start. i usually follow the following 3-tier architecture..
1. UI Layer
2. BLL - business logic layer
3. DAL - Data Access Layer
a. DTO / DAO
b. Gateway (contains the sql query/stored procedure and connection with DB)
now when i'm going to use the Entity Model Design,where the DBML/ .edmx File should be placed? Because many a times i'm using the DBML file as DTO because of the mapped objects.. in the same time, sometimes DBML ( .edmx file in .NET 4.0) contains CRUD methods and stored procedured method as well as methods with different selection operations,- which should be in Gateway. so where the .edmx file should be placed !?!! IN DTO namespace !? or in Gateway namespace!
moreover sometimes there is no need for the BLL which breaks the rules of inter-layer-communication (UI > BLL > DAL.Gateway)! what makes me confuse is, what should be the ideal n-tier architecture when i'll use the ADO.NET Entity Model Design Framework

I was told by my manager that in a few weeks or so we would be getting a bigger project and I need to be well versed with Design Patterns and N tier arcihtecture.
I would really appreciate if someone could provide me some links and also drop me a few sentences on how this things are useful?

I am try to create architecture design for WCF service.
We have WCF service that we have to expose to third party so then can request with xml and get back xml response.
The wcf service should do the following:
- Accept the request call with xml
- Check xml against the schema
- Parse the xml
- Authenticate the incoming xml by username and password that will be in xml
- Send back the response
If anybody can let me know what kind of design I can use or is there any pattern available that I can take it and then extend it as per my requirement.

I want to convert following PHP code to C#.
$client=new SOAPClient(API_URL."www/ws_rpc.php?wsdl&actor=fieldreport_actions&client=".API_KEY,array("uri"=>"SOME_URL","style"=>SOAP_RPC,"use"=>SOAP_ENCODED,"encoding"=>"UTF-8"));
$auth = $client->is_valid_panelist_login("login_type_email",$username,$password);
How can I do it? I found 1 sample at: Help me convert this PHP SOAP code to C# But this looks bit different.

For an ASP.Net website with calls through to a WCF Service:
Three web clients click the button that calls the WCF Service simultaneously.
Does the web server make 3 concurrent calls? (e.g. WCF Service receives 3 concurrent calls) one on behalf of each web client?

I am posting this as a part of my effort in searching the best possible design solution for my requirement. I am currently working on a complex server control(not user control) in asp.net which is going to be rendered into html elements on the client side.And those html elements needs to do a ajax call backs to the server using js/jquery. Here is the problem. As this is a serverside control and can be added into any application/domain. I dont want to have those callback services hosted separately. Is there any way that I can host those server callback services in the same library? If so, how can I access them from the client side?

I have 2 web services. They are identical in every respect except that one points to a test schema and the other one to production. I'm in the middle of writing the class that will use these web services but I'm not sure how to do what i'm trying to do.What I need is a class that does the work of consuming the web serivce, and I want to pass to it either the test or prod serice and and it be transparent insde of the class.
So..testSerive and prodSerice are idential, how can i have them inherit from something so that i can pass that something to my consumer class?

I'm working on a web application using VB.NET. In page load event am calling a remote web service which take time to bring the data. During this process none of the other contents on page are shown(render).
I want to call this remote web service asynchronously so that other data of page is displayed and web service data will be displayed when its available.

I have a fairly complex business application written in ASP.NET that is deployed on a hosted server. The site uses Forms Authentication, and there are about a dozen different roles defined. Employees and customers are both users of the application.
Now I have the requirement to develop a Windows Mobile client for the application that allows a very specialized set of tasks to be performed from a device, as opposed to a browser on a laptop. The client wants to increase productivity with this measure. Only employees will use this application.
I feel that it would make sense to re-use the security infrastructure that is already in place. The client does not need offline capability.
My thought is to deploy a set of web services to a folder of the existing site that only the new role "web service" has access to, and to use Forms Authentication (from a Windows Mobile 5/.Net 3.5 client).
I did see this question and I am aware of the limitations that Forms Authentication poses. Since security is not my primary motivator (I use SSL and can restrict access by IP address), but rather using existing user accounts and roles, my decision tree is somewhat different as well.

The message sent to browser is as follows:
The type My.API.Class is ambiguous: it could come from assembly '[on Temporary ASP.NET Files]' or from assembly '[on bin folder]'
The problem occurs when debugging a Web App, speciically when making a request to a WebMethod of a WebService.The project compiles just right. It generates My.Website.dll on bin folder and if I publish the Web Application. It works fine.The asmx file is on the root of the application. The CodeBehind file is on App_Code and its marked to be compiled to generate My.Website.dll.The way this person exposes its problem is somehow similar but I get starting to be lost when he talks about a proxy class and shared dlls I don't use.

Can some one inform me whether I need to replicate the same set of entities in the client which are similar to that of the ones in the server? I have planned to start a proj with service functions as wcf services and in turn they are getting referred in silverlight client application.
Incase if i need to consider casting to or back from the return value lists of service methods in the server, should i be creating entity class in the client application as well? Or is there a work around? Something like exposing the entities from the server just as the services functions?

there's an .aspx page that does absolutely nothing in the codebehind, but contains the markup for the page in the Design View. Then we have an .asmx web service that receives requests with JSON content-type. These are called by the JavaScript in the page. This web service returns .NET objects serialized to JSON in response to these JavaScript Ajax HTTP POSTs. I'd like to switch to MVC but am not sure to how switch this architecture. Basically what we're doing is two things:
1) Replying to GET /MyPage.aspx with HTML markup that represents the page
2) Replying to POST /MyPage.aspx/WebMethodName requests with .NET objects serialized to JSON.
It seems like MVC would be a good way to eliminate the need for a Page object (again, the codebehind isn't used--only the HTML markup in the .aspx file is) and an .asmx web service. No? What do I need to start changing to accomplish this switch? Is it straight-forward? Painful? Someone at work already has an MVC page running in the same directory as my Web Forms .aspx and .asmx web service, but I don't see anything in the directory about Routes, so I'm confused. He's got a Views, ViewModels, and Controllers subdirectories.

I'm planning to make an ASP.NET webserver that provides all kinds of functions, like an API. There will be quite alot functions that can easily be grouped (datasystem, userAccount, fileSystem, and so on). I can make multiple services (asmx files) into a single webserver, and let the clients connect to whatever service(s) they need. However, I'm not sure if it's a wise thing to do... Pack everything into 1 big service(1 asmx file), or split up into many smaller services? How about:
- performance/memory on the server (a client that connets with 1 or 6 services)
- Maximum connections (we will use a Windows XP Server edition computer)
There will be about ~30 computers using it. In a worst case scenario, they each computer could make use of 6 services at the same time, if I decide to split it up. A single client could make use of the fileSystem, account, dataSystem and several other things at the same time.
